The graph of g(x) resembles the graph of f(x)=x^2, but it has been changed. Which of these is the equation of g(x)?
siniylev [52]

Answer:

A.

Step-by-step explanation:

Anwer A has the following equation:

g(x)=\frac{3}{5}x^2-3

In this equation, we can calculated the intercept replacing x by 0, as:

g(x)=\frac{3}{5}0^2-3=-3

if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.

Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:

0=\frac{3}{5}x^2-3\\x_1=\sqrt{5}=2.236\\x_2=-\sqrt{5}=-2.236

It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.

So, the answer is A, g(x)=\frac{3}{5}x^2-3

Evaluate each expression if a=2, b=3 and c=4<br><br> A.) 2a+4b-c<br> B.) 6(a+c)-b
djyliett [7]

Answer:

Step-by-step explanation:

A.) 2a+4b-c:  Replacing a with 2, b with 3 and c with 4, we get:  

    2(2) + 4(3) - (4) = 4 + 12 - 4 = 12

B.) 6(a+c)-b:  Replacing a with 2 and c with 4, we get 6(2 + 4) - 3.

The work inside parentheses should be done first, resulting in 6(6) - 3.

This comes out to 33.

Find the equation of the line through the points (9,−2) and (1,6).
devlian [24]

Answer: y=-x+7

Step-by-step explanation:

Answer:

Your given points: (9,-2)and (1,6)

x1=9

y1=-2

x2=1

y2=6

Step-by-step explanation:

To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1

6-(-2)/1-9=6+2/1-9=8/-8=-1

SLOPE IS m=-1

Then take that slope u got and plug into this equation to find equation of the line

y-y1=m(x-x1)

y-(-2)=-1(x-9)

y+2=-x+9

-2. -2
